Schedule
When DL 3074 flies
DL 3074 flies ATL to MYR without a single fixed slot. Its most common scheduled departure was 22:30, used on 79 of 365 flights, with 22:45 (71 flights) and 22:35 (56 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 22:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 3074 runs 6 points better at 76.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 3074 quarter by quarter
DL 3074 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.2% on time and its weakest Jul–Sep 2025 at 67.4%, a swing of 15 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

- Oct–Dec 202592 flights78.0%
- Jan–Mar 202690 flights79.3%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 3074 ranged from 70.6% on Sunday to 82.0% on Friday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 3074 runs late
One category carries most of the weight here. Carrier accounts for 52% of the 5,226 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 52%Carrier
- 31%Late-arriving aircraft
- 11%National Airspace System
- 6%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,716 of the 5,226 delay minutes reported here. The split is drawn from 5,226 delay minutes reported on DL 3074.
Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
8.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
Every one of the 365 flights under DL 3074 in the data flew ATL to MYR. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 365 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
